You can control the bounty manager to hide the email lists on spreadsheet yourself, you don't need to make post about it on here, I'm guessing that this happens almost every time when a new bounty managers tries to manage a new project, no reputable bounty manager will do such thing
Previously, our data on postal mail really remained in many tables and this is quite dangerous for bounty hunters. I have had my email address hacked once. Through it you can enter backups of documents, saved account passwords, private keys from our wallets and much more. Therefore, of course, it is not worth putting our e-mail addresses on public display. Recently, I no longer see them in the table and this is correct. We are gradually developing certain safety rules for bounty hunters. I am also pleased that KYC is almost never carried out.
